I’m tougher on myself than any exercise coach when it comes to maintaining my fitness routine. I may be tired or feel sore or short of time to stretch or warm up, but I make myself squeeze in a workout anyway.
The Oura Ring 4, which isn’t cheap at $350 with a $6 monthly subscription, helps me overcome the guilt that goes with skipping a workout.

On days when I’m feeling a little exhausted and burnt out, seeing a low Readiness Score gives me the extra bit of reassurance I need to take a break rather than pushing myself into a run.
